Oregon winemakers warn against herbicide 2,4-D

Medford, Ore. -- With the heat in the forecast the Oregon Winegrowers Association is selling signs to warn people about 2, 4-D.

The signs alert farmers about the dangers the herbicide can have on grapevines.

"At 70 and 80 degree temperatures the herbicide will volatize up into the air and can be carried across the valley," Chris Hubert, vineyard manager for Results Partner, said.

2, 4-Dichlorophenoxyacetic Acid is a common herbicide used to kill broadleaf weeds. Hubert said grapes are highly susceptible to the chemical's ability to disrupt growth or kill vines. He said as Oregon's wine industry continues to grow getting the word out is key.

"Awareness is the biggest issue. We want people to be aware that they are responsible. It's called chemical trespassing," Hubert said.

He said there are plenty of pesticides that don't contain 2,4-D. But if you do use the chemical to make sure you follow directions on when and where you spray.

The OWA is selling the 12 by 18-inch signs for $21 from their office in Portland.
